PIPE,

Application filed June 17,

To all whom it may concern:

Be it known that I, JOSEPH Ismonn Ln BEL, a subject of the King of GreatBritain, residing at Montreal, Province of Quebec, Canada, have inventedcertain new and useful Improvements in Pipes; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The primary object of this invention, which is a smoking means forretaining moisture and nicotine from the tobacco in such a manner thatthe same cannot be drawn into the mouth through the same. The inventionresides in the formation of a moisture chamber in the stem of the pipe,the chamber being formed separate from the passage and in communicationtherewith only through the bowl,

A further object of the invention is a pipe so constructed that duringthe operation of smoking, there will be no suction on the nicotinedeposited in the bowl.

As a pipe is'smoked, the tobacco is converted into a number of elementsincluding smokeand nicotine. An additional feature of the invention liesin the fact thattwo of these elements, namely smoke and nicotine, areseparated in the bowl, and are subsequently prevented from mixing withone another after separation. In this respect, the invention is to bedistinguished from other pipes, in which the smoke and nicotine aredrawn together into the stem and are supposed to separate on their way:to the mouth-piece. I1

More specifically, the invention makes use of a moisture chamberformedin the stem of the pipe and beneath the draft passage. In ordertoavoid the entrance of nicotine and moisture into the draft passage, theinterior of the bowl isprovided with a projection disposed abovethedraft passage. By this means, the moisture and nicotine avoid said draftpassage and are directed the moisture chamber, the. entrance end thereofbeing of such configuration and disposition as to readily receive themoisture and nicotine which is urged downwardly as the burning of thetobacco continues. In this connection, it is to be noted that during theburning of the tobacco, the heat generated has the effect of forcing themoisture and nicotine downwardly, so that the tendency pipe, is theprovision of downwardly in the direction of 1922, Serial No. 569,024.

of such moisture and nicotine to proceed towards the moisture chamber ispositive rather than incidental.

The invention is illustrated in theaccompanying drawings, in which:

Figure 1 is a longitudinal section through the pipe;

Figure 2 is a similar View of the mouthpiece;

' Figure 3iis a similar view of the bowl and stem; and,

Figure 4 is a section on the line 4-4 of Figure 1 Referring to thedrawings by reference numerals, the pipe consists of a hollow bowl 1provided with a stem 2. A draft passage 3 is formed through the stem andcommunicates with the bowl in the usual manner. A moisture chamber 4 iscut through the stem in substantial parallel relation with the draftpassage, and is disposed therebeneath. This chamber also communicateswith "the bowl, as at 5, the opening 5 being spaced inwardly from theinner end 3 of the draft passage. The mouthpiece 6 is connected to thestem by means of an abutment 7 which is threaded for engagement with theforward portion 8 of the moisture chamber. The stem has formed thereinthe usual passage 9 which communiturned into its proper position. It isto be noted that the joint between the draft passages through themouth-piece and stem is flat in contrast with the usual threaded jointfund in the corresponding position in other pipes. It is well known thatwhere a screw joint occurs in the draft passage, there is anaccumulation of nicotine and other clogging substances. This inconven-'cates with the passage 3 when the stein is' ienceis eliminatedby meansof the flat joint described above. I j I A. stripof absorbent material10 is inserted in the abutment 7 and eXtendsinto the chamber 4:. Thismaterial serves to take up the moisture as the latter deposits in thestem and mouth-piece.

1 above the inner end of the draft passage 3. As the result of thisconstruction, the nicotine and moisture which are forced downwardly asthe burning continues, are simultaneously directed somewhat laterally inorder to avoid entering the draft passage. Consequently this materlalenters the moisture chamber through the opening 5, the latter extendingbeyond the inner end of the draft passage 3, as a result of which theentrance of the moisture and nicotine into the chamber 4: is greatlyfacilitated. It will be observed that the moisture chamber 4 hasabsolutely no direct communication with the draft passage 3, whereby anypossibility of the moisture entering the draft passage is eliminated.

In the ordinary use of a pipe, the burning tobacco is: changed to ashes,and the moisture and nicotine from such burnt tobacco is forceddownwardly into the bowl under the action of the heat produced.Consequently, the moisture concentration of the remainingtobaccoincreases as the smoking progresses. Finally the concentration of themoisture becomes so great that the tobacco at the bottom of the bowl issaturated with it, and. such moisture is then drawn through In thepresent invention, the elements produced in the burning, including thesmoke, are separated in such manner that the smoke and moisture followdifferent paths. Specifically, the

'moisture and nicotine are prevented from entering the draft passage 8by means of the projection 3, as already pointed out. Under the burningof the tobacco, the moisture and nicotine are forced downwardly into theopening 5, thereafter being absorbed in the chamber 4. The smoke, beinglighter than the moisture and nicotine, is affected by the draftproduced in the draft passage, whereupon it is pulled therein. Becauseof the space between. the inner end of the passage 3 and the opening 5,an excessiv draft through the smoke passages will not lift the moisturefrom the chamber 4:, especially when the same has been absorbed in thesubstance 10. It has been found that even an excess of draft through thesmoke passages will not raise the moisture of the moisture chamber. Infact, it is physically impossible to raise such moisture and nicotineafter the same have reached a level below the lower wall of the draftpassage 3, especially since there can I lVhile a specific embodiment ofthe invention has been illustrated and described, it is to be understoodthat various alterations in the details of construction may be madewithout departing from the spirit of the invention as indicated by theappended claims.

Having thus fully described the invention, what I claim as new anddesire to secure by Letters Patent is 1. A smoking pipe comprising abowl and a stem, said stem having formed therein a draft passage and amoisture chamber, both in communication with the bowl, said chamberbeing separate from the passage, and a mouth-piece having an abutmentadapted to be received in said chamber.

2. A smoking pipe comprising a bowl and a stem, said stem having formedtherein a draft passage and a moisture chamber, both in communicationwith the bowl, said chamber being separate from the passage, amouth-piece. having an abutment adapted to be received in said chamber,and an. absorbent substance carried by said abutment and extending intothe chamber.

3. A smoking pipe comprising a bowl and a stem, said stem having formedtherein a draft passage and a moisture chamber, both in communicationwith a bowl, said chamber being separate from the passage and having itsentrance opening disposed beyond the inner end of the draft passage inthe stem, and an inwardly extending projection formed within the bowl.and disposed above the draft passage.

4. A smoking pipe comprising a bowl and a stem, said stem having formedtherein a draft passage and a moisture chamber, both in communicationwith the bowl, said chamber being separate from the passage, amouth-piece having a threaded abutment adapted to be received in saidchamber, an absorbent substance carried by said abutment and extendinginto the chamber, the joint betweenthe mouth-piece and stem bemg flat atthe junction of the draft passages therein.

In witness whereof I have hereunto set my hand.
